For what values does c have no solutions?

defon

Solve for c :

x⁴ + cx² + 100 = 0

cx² = -(x⁴ + 100)

c = - (x⁴ + 100)/x²

If x = 0, the right side is undefined and c would have no solution.

Answer:

Manufacturers has to produce 63 DVD/Blu-Ray players to achieve a minimum cost of $644

Step-by-step explanation:

The cost equation is given as:

$C=0.04x^2-5x+800$

This is a quadratic equation in general form, which is:

$y=ax^2+bx+c$

Matching, we can say:

a = 0.04

b = -5

c = 800

The minimum occurs at $x=-\frac{b}{2a}$

and the minimum value would be to place that "x" value into the equation.

First, we find the minimum using values of a and b:

$x=-\frac{b}{2a}=-\frac{-5}{2(0.04)}=\frac{5}{0.08}=62.5$

Plugging this into original, we get:

$C=0.04x^2-5x+800\\C=0.04(62.5)^2-5(62.5)+800\\C=643.75$

Rounding off to nearest whole number, we can say:

Manufacturers has to produce 63 DVD/Blu-Ray players to achieve a minimum cost of $644
